When placing an I-Beam or any wide flange sections, the shapes are getting no webs in the model. The webs are also missing in the preview.
1. Go to your Shapes Database which can be found at C:\ProgramData\Bentley\ProStructures CONNECT Edition\Configuration\WorkSpaces\<Your Workspace>\Standards\ProStructures\Shapes\*.mdb.
2. Assign values for GEO_KDES column. The values on this column should not be less than fillet weld radius (GEO_R). You may assign Kdes or Kdet depending on the code preferences.
Kdes or Kdet = design/detailing distance from the outmost edge of the flange to the web fillet toe.
R = fillet radius
Relationship: K = R + flange thickness
Following the above resolution, you may now check the shapes displaying appropriately in the preview and in the 3D model space.
